问题 I am using map on my application, For pin drop, I want to set user's image instead of default pin. I am downloading users image and setting it as per code I paste below. For different scale of devices I am using image name as per device scale like eg., 1 For non retina device - pin.png (size 30 x 30) 2 For retina devices - pin@2x.png (size 60 x 60) 3 For 6+ device - pin@3x.png (size 90 x 90) Here for 1 and 2 working fine and image loads perfect But for 6+ (3x scale) it's not working What's

问题 I've got a problem with my MKAnnotationView s when MKUserTrackingModeFollowWithHeading is enabled on the MKMapView. I positioned my images using the centerOffset property of the MKAnnotationView. Specifying the coordinates of the pin's tip relative to the coordinate system at the center of the image is somewhat counter-intutive, but I came up with the following formula: annotationView.centerOffset = CGPointMake(imageWidth/2.0 - tipXCoordinate, imageHeight/2.0 - tipYCordinate); This works fine

Here is what I want to do: I have a map (an MKMapView object) and when I touch it, I put a pin at the touch point, then some computation is performed and this gives me a second point on the map. I put a second pin on
